Пошаговое объяснение:

3х+6у-10х+5у+х-3у=8у-6х

Answer 2

Let's simplify the expression step by step:

1. Start by distributing the coefficients to the terms inside the parentheses:

   3*(x + 2y) = 3x + 6y -5*(2x - y) = -10x + 5y (x - 3y) = x - 3y

2. Now, we can combine like terms by adding or subtracting them:

   (3x + 6y) - (10x - 5y) + (x - 3y)

3. Perform the subtraction:

   3x + 6y - 10x + 5y + x - 3y

4. Combine like terms again:

   (3x - 10x + x) + (6y + 5y - 3y)

5. Perform the arithmetic:

   -6x + 8y

So, the simplified expression is:

-6x + 8y
